Amenable deaths among adults with intellectual and developmental disabilities including Down syndrome: An Ontario population-based cohort study.

Background: Rates of death and avoidable deaths are reportedly higher among people with intellectual and developmental disabilities. This study contributes to our understanding of how mortality and intellectual and development disabilities are associated.

Method: General population and intellectual and developmental disabilities adult cohorts were defined using linked administrative data.

Matching Special Olympics registration data with administrative health databases: Feasibility and health status differences in children and youth with IDD.

Background: Children and youth with intellectual and developmental disabilities (IDD) experience health disparities. What is unknown is if data collected from children and youth with IDD who participate in Special Olympics is representative of children and youth with IDD who do not.

Objectives: Aim 1: determine the feasibility of matching a database of registrants from Special Olympics Ontario (SOO), with population-based health services databases in Ontario, Canada housed at ICES.

Psychiatric disorders in adults with cerebral palsy.

Background: Cerebral palsy (CP) is one of the most common neurological conditions in childhood. Individuals with CP often experience various secondary conditions, including intellectual disability (ID), medical conditions, and psychiatric issues. A large number of youth with CP have psychiatric disorders; however, few studies have examined the prevalence of psychiatric issues in adults with CP at the population-level.

Looking across health and healthcare outcomes for people with intellectual and developmental disabilities and psychiatric disorders: population-based longitudinal study.

Background: Intellectual and developmental disabilities (IDDs) and psychiatric disorders frequently co-occur. Although each has been associated with negative outcomes, their combined effect has rarely been studied.

Aims: To examine the likelihood of five negative health and healthcare outcomes for adults with IDD and mental health/addiction disorders (MHAs), both separately and together.

Repeat Emergency Department Visits for Individuals With Intellectual and Developmental Disabilities and Psychiatric Disorders.

Although individuals with intellectual and developmental disabilities (IDD) and psychiatric concerns are more likely than others to visit hospital emergency departments (EDs), the frequency of their returns to the ED within a short time is unknown. In this population-based study we examined the likelihood of this group returning to the ED within 30 days of discharge and described these visits for individuals with IDD + psychiatric disorders ( = 3,275), and persons with IDD only ( = 1,944) compared to persons with psychiatric disorders only ( = 41,532). Individuals with IDD + psychiatric disorders, and individuals with IDD alone were more likely to make 30-day repeat ED visits.
